.NET's non-root UID 64198 exceeds Debian's UID_MAX of 60000

Debian Bookworm has a UID_MAX set to 60000, resulting in this warning when creating a non-root user:

```
#6 [3/3] RUN groupadd         --gid=64198         app     && useradd -l         --uid=64198         --gid=64198         --create-home         app
#6 0.610 useradd warning: app's uid 64198 outside of the UID_MIN 1000 and UID_MAX 60000 range.
